For your grep lines, add
>/dev/null 2>&1
to the end of each to avoid printing the matched line, or add the "-q" option to the last grep command on the line (to stop it printing out the matching line, but only if your grep command supports it)
In your "if" tests for the result of the grep, use:
if [ $? -eq 0 ]
(no quotes needed)
Increment the counter "n" when you fail instead of when you succeed - that way, the test at the end is
if [ $n -eq 0 ]
then
all is OK
else
there was an error
fi
this saves you having to keep $PRDN in step if you add further tests.
Do the "grep $DATE /nsr/logs/donelist.log |grep dxnprdap" command once, and put the output in a temporary file:
grep $DATE /nsr/logs/donelist.log |grep dxnprdap > /tmp/tst.grp
Then check that /tmp/tst.grep file for /usr/ /u01, /u02 etc. Remove the file at the end of the script.
If you do the above, and put the output into /tmp/tst.grp, you can simplify the tests to
if grep -q /u01 /tmp/tst.grep
then
echo /u01 OK
else
echo /u01 failed
let ""n+=1"
fi
(assuming that your "grep" supports the "-q" option to suppress output. If not, add ">/dev/null 2>&1" to the end of the line)
